Product Details
Configured for precision shaft displacement monitoring in rotating machinery, the Epro PR6426/010-140 + CON011/916-120 (PR6426/010-140 Eddy Current Sensor) provides direct physical electrical execution for measuring relative radial and axial shaft vibration. The system utilizes electromagnetic induction to generate a linear voltage output proportional to the gap between the 8 mm probe tip and the observed conductive target, facilitating continuous rotor dynamics assessment via a 120-meter extension cable interface.

Eddy-Current Probe Scaling and Rotor Dynamics
The PR6426 system is designed to provide linear signal output across the specified transducer measuring range of 2.0 mm. Proper eddy-current probe scaling is required to maintain the accuracy of vibration data when interfaced with monitoring instrumentation. During commissioning, operators must perform a gap voltage validation against the -10 VDC target, ensuring the probe tip is positioned within the linear segment of the transducer's sensitivity curve. This calibration is necessary to capture accurate rotor dynamics, including shaft orbits and eccentricities, while minimizing the influence of cross-talk suppression limitations in multi-probe array configurations.
Frequently Asked Questions (FAQ)
Q: What is the impact of the 120-meter cable length on signal fidelity?
A: The system is designed to compensate for the impedance characteristics of the 120-meter extension cable. Ensure that the specific transducer model matches the cable impedance to prevent signal attenuation and frequency response degradation within the 0 to 10,000 Hz range.
Q: How is the gap voltage validated during site installation?
A: Utilize a high-impedance digital multimeter to measure the output voltage at the monitoring system interface. Adjust the probe distance from the shaft target until the output reads -10 VDC, which corresponds to the midpoint of the linear operating range.
Field Installation Guidelines
- Inspect the 8 mm probe tip for mechanical damage or metallic debris that could introduce non-linearities into the output signal.
- Secure the probe in a rigid mounting bracket to prevent resonant vibrations from contaminating the displacement data.
- Terminate the coaxial cable using the provided CON011 connectors, ensuring all connections are shielded and grounded at the rack entry point to minimize electromagnetic interference.
- Route the 120-meter cable through dedicated, non-metallic conduits if possible to maintain signal integrity and avoid inductive coupling with high-voltage power lines.
- Perform a full-scale static calibration check after installation to confirm that the displacement output remains consistent with target gap measurements.
